Composite microbial fertilizer for controlling soil-borne disease and preparation method thereof

Abstract

The invention discloses a composite microbial fertilizer for controlling soil-borne disease and a preparation method thereof. The composite microbial fertilizer for controlling soil-borne disease is prepared from the following raw materials in parts by weight: waste livestock / fowl feather, rice bran, dry manure, weathered coal, biochar, a composite microbial inoculant, humic acid, bentonite, potassium sodium tartrate, citric acid, copper sulfate and ferrous sulfate. The composite microbial inoculant is prepared from the following raw materials in parts by weight: Bacillus megaterium, Bacillus mucilagimosus krassilm and Paenibacillus sabinae. The composite microbial fertilizer contains abundant various microbes, and the composite microbial inoculant is added to increase the beneficial bacterium content, so that the composite microbial fertilizer becomes a microbe resource pool. After being applied by drip irrigation and spraying, the composite microbial fertilizer can adjust the phytoedaphon structure, enhance the soil microbe diversity, improve the microecological environment of the soil and reduce the biosphere of the phytopathogen, thereby achieving the goal of controlling soil-borne disease.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a compound microbial fertilizer capable of preventing and treating soil-borne diseases and a preparation method thereof. Background technique [0002] As a large agricultural country in my country, agricultural production plays a vital role in the national economy, and fertilizer is an important factor affecting the output and quality of agricultural production. However, most fertilizers currently on the market have deficiencies in nutritional components, that is, while increasing yields, certain nutrients cannot keep up with demand, or focus on stimulating crop growth, leading to nutrient deficiencies, etc., resulting in poor stress resistance of crops and low yield. The reduction and quality decline cannot meet the needs of agricultural production at this stage. [0003] In addition, due to the long-term use of chemical fertilizers in our country for many years, the shorta...

AI Technical Summary

Problems solved by technology

[0004] With the application of microbial technology in agriculture, many functional bacteria are also widely used in the fields of pesticides and fertilizers, which provide effective methods and solutions for the realization of environmental protection, pollution-free and efficient agricultural production. Therefore, the biological fertilizers in which many functional bacteria participate It has emerged as the times require, but the current biological fertilizers can only be used as auxiliary fertilizers to reduce the amount of chemical fertilizers and pesticides, but cannot fundamentally solve the problem of soil compaction
